Hi Bill, as someone has helped me I shall attempt to help you. It's a simple thing to do really so all you need to do is go to the 'AppData/Roaming/Poser Pro/ "Version of Poser"' folder as mentioned earlier in Windows Explorer and right click the Poser.ini file, choose Copy then right click again and choose Paste. This should make a backup of your Poser.ini file (Mine's called Poser - Copy.ini). This will be the backup of your existing .ini file. You can then edit the Poser.ini file itself. If anything goes wrong you can delete the Poser.ini file you edited and rename the copy back to the original name. Remember to make a copy again though before you edit it again.

Just to help in case you're not sure how to access AppData, here's a pic of a quick way to get there.
